Specification of Letters Patent.

Patented Nov. 25, 1913.

Application filed January 18, 1918. Serial No. 742,793.

This invention relates to sprayersand has for its object a spraying device which is adapted to mix a poisonous solution with a stream of water such as is used in a garden hose or other water line. The device is effective for the purpose for which it is intended, is compact in arrangement and eco nomical to manufacture.

The points of novelty and the advantageous features will more fully appearin the specification following.

In the drawings :Figure 1, is a longitudinal section of the mixing device. Fig. 2, is a cross section on the line 2--2 ofFig. 1. Fig. 3, is an elevation of the sprayer attached to a faucet.

A container 1 of cylindrical form is provided and is internally screw-threaded at each end. Into these threads screws, at each end, an end piece, one of which is indicated on the drawings as 2 and the other I as 3. The end piece 2 is threaded at two places and has. an opening clear through at these locations. The one-opening is for the passage of the pipe 4, the other opening is for the passage of the branch or elbow pipe 5. The end piece 3 has two openings, each of which is'partially screw-threaded. The opening 6 is closed by a screw plug 7 and this opening is forthe introduction of the solution which is normally contained in the container. The other opening is in line with a similar 0 ening of the end piece 2 and is intended or the passage of the pipe 4. Each of these 0 enings in the end pieces for the passage 0 the pipe 4 contains a packing ring 8 and a threaded sleeve or nut 9 by which the pipe 4 may be securely held in place and packed with respect to the end pieces to prevent leakage of the solution in the container. The branch ipe or elbow 5 has two'portions that are stantially right angles. One portion is lsposed at 511 h serew-threaded as at 10 to screw into the side of the pipe line 4 and to divert part of the water therefrom. The other portion fits into the hole of the end piece 2 and is secured therein by a nut 11 and packed to prevent leakage b I the packing ring 12. This elbow 5 has-an externally and internally screw-threaded extension 13 that acts as a valve casing and into which screws the needle valve 14 that regulates the passage of the elbow at the angle of the conduit. A cap 15 screws over the end of the extension or valve casing. v

A goose neck or a receiving pipe 16 of small bore is connected with the pipe 4 at about its midpoint and serves to take some of the solution out of the container and introduce it into the pipe v4. The solution contained in the container 1 may be a solution of arsenic of lead, sulfur of lime or any other insecticide. This solution is. introduc'ed into the container through the opening 6 by'the removal of the screw-plug 7. The pipe 4 is provided with a swiveling coupling 17 'at one end and a threaded coupling 18 at the other, so that it may be attached to a hose line 19 that is connected with a faucet or cook 20 of the city water mains. The water under pressure passes through the hose 19 and into the Plpfi 4 where part of it enters the elbow 5 and forces its way into the container. The passage of the elbow 5 is very much smaller than the passage of the pipe 4 and it is regulable by the valve 13. .This' puts the solution in the container 1 under pressure and forces it out gradually through the goose neck or receivin pipe 16 into the main water line. It Wlll, readily be seen that the rapidity at which the solution is driven from the container 1 may be regulated by the 'shrubberies, etc.

One of the features of this invention is that the full pressure'of. the city'mains may be utilized in the hose-and one-has the convenience of sprinkli the-city water and at the same time the a vantage of being able to contaminate the water so as to make it a spraying solution to kill and the about with the user. as hemoves about the lawn or on the ground. j The goose neck 16 prevents the solution running out when the device is not in use, for it will readily be 21 on the elbow pipe for seen that when the water is turned off at the faucet very little of the solution can run'out into the pipe 4 by reason of the curvature of the goose neck. 16.

In connection with the maintenance of th container in the position shown in the drawings and with the elbow pipe 5 near the top of the container, 1 em 'loy a curved end the purpose of directing the incoming water under pressure toward the bottom of the container. to stir up the heavy particles 'of'the solution which are liable to seek the bottom and which otherwise might-not be properly mixed and forced out intothe main pipe.

In order to make the different parts-capable of assembly, I make the elbow, in two portions whose adjacent ends are pipethreaded and a coupling-nut 5 is adapted to screw onto these ipe-threaded ends by reason of being itsel pipe-threadedr They are, therefore, oined in a water ti ht union.-

This allows the bentpipe' 21 to, e passed through the end piece/2 'from the inslde before the end piece is screwed to the container.
